Echinodermata are more closely related to Mollusca than they are to Chordata
- C.
Mollusca and Arthropoda probably evolved before Porifera
- D.
Annelida and Arthropoda evolved from Echinodermata

Describe past environments and the history of life
- B.
Study present ocean temperatures at different depths
- C.
Analyze the chemical composition of sedimentary rocks and minerals
- D.
Describe the details of the process by which life began on Earth
- 4.The process by which a species passes out of existence is known as
